XSL and Excel

I have an xml file saved from Excel. The first cell in the first row contains a number that represents the row my column headings will start. I'm trying to get the value from this cell and put it into a variable for later on.

An excert from my original xml file:

7

Some Bank

The only thing I can guarentee with the original file is this 1st cell will contain the row number the column headings start on. So my question is how do I reference that first cell? I've tried putting the value out in a comment just to see if I can reference it and it does not like it.

-- this value is 8

My output xml looks something like this:

<?xml version="1.0" encoding="UTF-8"?>

Any/all help is greatly appreciated due this being completely new to me.
